Description

[0001] This application is a divisional application of the Chinese patent application with the application date of June 22, 2020, application number 2020105762990, and invention name "Anti-fall device for battery swapping equipment, battery swapping equipment and anti-fall method for battery swapping equipment". Technical Field

[0002] The present invention relates to a battery swapping equipment anti-falling device, battery swapping equipment and a battery swapping equipment anti-falling method. Background Art

[0003] When replacing batteries in existing electric vehicles, it is usually necessary to remove the depleted batteries from the electric vehicles and transport them to the charging racks, and to remove the fully charged batteries from the charging racks and transport them to the electric vehicles. The charging racks usually store batteries in a stacked form, so when the battery replacement equipment is removing or placing batteries, it is necessary not only to move the battery replacement equipment horizontally, but also to move the battery replacement equipment vertically.

[0004] If the battery swapping device fails, stalls, or loses power during vertical movement, the battery swapping actuator will fall out of control or even fall freely, thus damaging the battery swapping device. The battery pack on the battery swapping device will also be damaged, and in severe cases, it may even cause deflagration and explosion after the battery pack is damaged. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the battery swapping equipment lacks safety protection after a failure or power failure, and may fall out of control, causing damage to the battery swapping equipment and the battery pack, thereby creating a safety hazard. A battery swapping equipment anti-falling device, a battery swapping equipment and a battery swapping equipment anti-falling method are provided.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A battery swap device anti-falling device is used in the battery swap device, wherein the battery swap device includes a battery swap actuator for disassembling and assembling a battery pack, and is characterized in that the battery swap device anti-falling device includes:

[0008] A locking mechanism, which is connected to the battery swapping actuator and has a first state and a second state. When the locking mechanism is in the first state, the locking mechanism is engaged with the battery swapping device to prevent the battery swapping actuator from moving upward or downward; when the locking mechanism is in the second state, the locking mechanism is disengaged from the battery swapping device.

[0009] In this solution, the locking mechanism is used to realize emergency braking when the battery swap actuator stalls and falls due to a fault. Among them, the faults include power failure of the battery swap device, damage to the power device driving the battery swap actuator, and excessive descent speed of the battery swap actuator. In the first state, the locking mechanism engages to lock the battery swap actuator to prevent the battery swap actuator from continuing to move. Once the fault is resolved, the locking mechanism returns to the second state and disengages from the battery swap device and does not affect the normal lifting and lowering of the battery swap actuator.

[0010] Preferably, the locking mechanism has an extension portion connected to the battery swap actuator, and the battery swap device has an abutment portion. When the locking mechanism is in the first state, the extension portion downwardly abuts against the abutment portion.

[0011] Relative to the lifting and lowering movement of the battery swap actuator, a relatively fixed abutment portion provides resistance to prevent further descent for the locking mechanism; during the locking process, the protruding portion abuts downward on the abutment portion, and the impact force generated by the locking is transmitted to the abutment portion through the protruding portion. At this time, the abutment portion provides an upward supporting force for the entire battery swap actuator, thereby effectively playing an anti-fall blocking role and, at the same time, avoiding damage to the abutment portion due to excessive gravity of the battery swap actuator and the battery pack it carries.

[0012] Preferably, the locking mechanism further comprises a driving portion, wherein the driving portion is connected to the extending portion and is used to drive the extending portion to extend or retract, so that the locking mechanism is switched between the first state and the second state.

[0013] By driving the extension or retraction of the extension part by the driving part, the state switching of the locking mechanism is realized simply and effectively. When the extension part is extended, the locking mechanism is engaged and connected with the battery swapping device to be relatively fixed, and when the extension part is retracted, it can avoid other structures so as not to affect the lifting and lowering of the battery swapping actuator.

[0014] Preferably, the battery exchange device is provided with a rack, wherein the rack has a plurality of the abutment portions arranged along the height direction.

[0015] The rack extends in the height direction and can completely cover all heights of the battery swap actuator during the lifting process. Therefore, by setting multiple abutment parts on the rack, the moving distance between the extension part and the abutment part can be shortened, so that the battery swap actuator of any height can engage with the abutment part without moving too much distance when it fails or stalls, so that it can brake in time.

[0016] Preferably, the battery exchange device has a frame, and both sides of the frame are longitudinal beams, wherein the battery exchange actuator is configured to be movable back and forth along the height direction of the longitudinal beam, and the rack is arranged on the longitudinal beam.

[0017] The extended portion of the battery swap actuator directly acts on the longitudinal beam, and the longitudinal beam, as a part of the frame, has sufficient strength to provide sufficient anti-fall resistance and supporting force for the battery swap actuator.

[0018] Preferably, the extending portion is a card plate, one end of the card plate is connected to the battery replacement actuator, and the driving portion is connected to the other end of the card plate and drives the end of the card plate to extend or retract.

[0019] The structure of the card is simple, which makes it easy to switch between states. If the card is damaged during use, it can also reduce the cost of replacement, which is conducive to reuse.

[0020] Preferably, the driving part includes an electromagnetic push rod, which is connected to the card plate, wherein an elastic element is provided on the electromagnetic push rod, and the elastic element is initially in a compressed state. The elastic element is used to pop out the electromagnetic push rod and drive the card plate to extend through elastic force when the electromagnetic push rod loses power, so that the card plate engages with the abutment part.

[0021] The electromagnetic push rod can respond to the control signal in time to drive the extension and retraction of the card in time, which is conducive to rapid braking in case of faults. Under normal conditions, the electromagnetic push rod is fixed under the action of magnetic force to pre-tighten the elastic element, so that the card remains in a retracted state; once a fault occurs, the electromagnetic push rod is no longer energized by controlling the electrical signal, the magnetic force of the electromagnetic push rod disappears, and the spring in the pre-tightened state quickly pops out under the elastic action to move the electromagnetic push rod, so that the card is extended in time and connected with the corresponding abutment.

[0022] Preferably, the elastic element is a compression spring. In other alternative ways, other elastic elements that increase the elastic force in the axial direction of the electromagnetic push rod can also be used.

[0023] Preferably, the anti-falling device of the battery exchange equipment includes a mounting base connected to the battery exchange actuator, one end of the clamping plate is connected to the mounting base and can rotate relative to the mounting base, a through hole is provided on the mounting base, and a connecting element is connected to the electromagnetic push rod, and one end of the connecting element passes through the through hole and is connected to the other end of the clamping plate.

[0024] In order to realize the extension and retraction of one end of the card, the end fixed to the mounting seat is set to a structure that can rotate relative to the mounting seat, so that the extension and retraction of the card are smoother. The card is extended or retracted by rotating under the elastic force of the elastic element or the magnetic force of the electromagnetic push rod. The motion structure of the entire card and the electromagnetic push rod is simple and reliable. At the same time, the extended end of the card can respond to the action of the electromagnetic push rod in time, which improves the reaction speed in the event of a fault.

[0025] Preferably, the connecting element comprises a connecting cap and a connecting rod, the connecting rod is connected to the electromagnetic push rod, and the connecting cap connects the clamping plate to the other end of the connecting rod.

[0026] The connecting cap and the connecting rod connect the card plate and the electromagnetic push rod. The connecting rod and the connecting cap are also very convenient to disassemble, which is conducive to replacing the card plate. The electromagnetic push rod will not directly contact and wear with the card plate. The parts prone to wear are set at the connecting rod and the connecting cap with simple structure and low cost, which can reduce the difficulty of replacement and replacement cost.

[0027] Preferably, the card plate is provided with a through hole, a groove platform is formed around the through hole, the end of the connecting cap abuts against the surface of the groove platform, and the connecting rod abuts against the side of the card plate opposite to the groove platform.

[0028] The end of the connecting cap abuts against the groove platform, which has a limiting function and can always keep the card between the connecting cap and the connecting rod during the repeated retraction and extension of the card, so that the elastic action of the elastic element generates a thrust on the card to extend it.

[0029] Preferably, a right-angle connecting plate is provided on the side of the battery swapping actuator, one side of the right-angle connecting plate is connected to the battery swapping actuator, and the other side is connected to a mounting seat, wherein the driving part and the clamping plate are respectively connected to both sides of the mounting seat.

[0030] The driving part and the card plate are arranged on the side of the battery replacement actuator through the right-angle connecting plate. The right-angle connecting plate can be replaced as a whole, or right-angle connecting plates of different specifications can be arranged according to the corresponding distance with the abutment part, so that the card plate can be normally engaged with the abutment part.

[0031] Preferably, one end of the clamping plate away from the mounting seat has an inclined surface, and when the clamping mechanism is in the first state, the clamping plate is extended to make the inclined surface horizontal so as to engage with the abutting portion in place.

[0032] After the card is extended into place, the inclined surface at the end is also switched to a horizontal state, so that it can be completely fitted with the abutment part, and the vertical support force can be fully transmitted to the battery replacement actuator, effectively preventing the battery replacement actuator from moving further. In addition, during the rotation and retraction of the card, the inclined surface can quickly detach from the abutment part and will not interfere with the abutment part.

[0033] Preferably, the battery swapping device also includes a speed detection mechanism, which is arranged on the top crossbeam of the frame and is used to detect the lifting and lowering speed of the battery swapping actuator. When the lifting and lowering speed is greater than a preset speed range, the control unit of the battery swapping device controls the locking mechanism to switch from the second state to the first state.

[0034] The speed detection mechanism can be a conventional detection device such as a laser speed meter, which can detect the speed of the battery swap actuator to determine whether a fault occurs in the battery swap actuator, and can promptly control the start-up positioning mechanism after a fault occurs.

[0035] A battery swapping device is characterized in that it comprises a battery swapping device anti-falling device.

[0036] Preferably, anti-falling devices for the battery swapping equipment are respectively provided on both sides of the battery swapping equipment.

[0037] A method for preventing a battery swapping device from falling is characterized in that it is implemented by using the battery swapping device for preventing a battery swapping device from falling, and includes:

[0038] Detect the lifting and lowering status of the battery replacement actuator.

[0039] The locking mechanism is controlled to switch between the first state and the second state according to the lifting state.

[0040] Preferably, the lifting state includes the lifting speed of the battery swap actuator. When the lifting speed is greater than a preset speed range, the locking mechanism is controlled to switch from the second state to the first state so that the locking mechanism is engaged and connected with the battery swap device, thereby preventing the battery swap actuator from moving.

[0041] The positive and progressive effect of the present invention is that the present invention realizes emergency braking when the battery swap actuator stalls and falls due to a fault through a locking mechanism. When the battery swap equipment loses power, the power device driving the battery swap actuator is damaged, or the descending speed of the battery swap actuator is too high, the locking mechanism is engaged to lock the battery swap actuator and prevent the battery swap actuator from continuing to move. This prevents the battery swap actuator from being damaged by impact and improves the safety of the battery swap equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0053] like Figure 1 As shown, this embodiment discloses a battery swapping device, which includes a battery swapping actuator 2, a frame 1, a speed detection mechanism 3, and a battery swapping device anti-falling device 4. Among them, the frame 1 includes a longitudinal beam 11. The battery swapping actuator 2 can be raised and lowered along the length direction of the longitudinal beam 11. Figure 2 As shown, the battery swap device anti-falling device 4 is connected to the battery swap actuator 2. In this embodiment, it is further configured that the battery swap device anti-falling devices 4 are respectively provided on both sides of the battery swap actuator 2.

[0054] The speed detection mechanism 3 is arranged on the top cross beam 12 of the frame 1 and is used to detect the lifting and lowering speed of the battery swap actuator 2. When the lifting and lowering speed is greater than the preset speed range, the control unit of the battery swap device controls the locking mechanism 40 to switch from the second state to the first state.

[0055] The speed detection mechanism 3 can be a conventional detection device such as a laser speed meter, which detects the speed of the battery swap actuator 2 to determine whether the battery swap actuator 2 is faulty. Thus, the control unit can control the start-up of the locking mechanism 40 in a timely manner.

[0056] like Figure 2 and Figure 3As shown, this embodiment discloses a battery swapping device anti-falling device 4, which includes a locking mechanism 40, which is connected to the battery swapping actuator 2 and has a first state and a second state. When the locking mechanism 40 is in the first state, the locking mechanism 40 is locked and connected with the battery swapping device to prevent the battery swapping actuator 2 from moving upward or downward; when the locking mechanism 40 is in the second state, the locking mechanism 40 is disengaged from the battery swapping device.

[0057] In this embodiment, the locking mechanism 40 is used to realize emergency braking when the battery swap actuator 2 stalls and falls, or when a fault occurs during the ascent and the actuator 2 falls. Among them, the first state includes power failure of the battery swap device, damage to the power device driving the battery swap actuator 2, and excessive speed of the battery swap actuator 2. In the first state, the locking mechanism 40 is engaged to lock the battery swap actuator 2 to prevent the battery swap actuator 2 from continuing to move. Once restored to the second state, the locking mechanism 40 is disengaged and does not affect the normal lifting and lowering of the battery swap actuator 2.

[0058] like Figure 3 As shown, the positioning mechanism 40 of this embodiment has an extension portion connected to the battery replacement actuator 2. The extension portion is a card plate 43. The card plate 43 has a simple structure, and can also reduce the cost of replacement when the card plate 43 is damaged during use, which is conducive to reuse.

[0059] like Figure 3 As shown, one end of the card plate 43 is connected to the battery replacement actuator 2, and the other end of the card plate 43 is connected to a driving part 41 and drives the end of the card plate 43 to extend or retract. The driving part 41 is connected to the card plate 43 and is used to drive the card plate 43 to extend or retract, so that the card mechanism 40 is as shown in FIG. Figure 4 The first state shown and Figure 5 Switching between the second states shown.

[0060] like Figure 4 As shown, when the locking mechanism 40 is in the first state, the clamping plate 43 is downwardly abutted against the abutting portion 51. During the locking process, the abutting portion 51 provides support force as a fixed part, thereby holding and supporting the clamping plate 43. The impact force generated by the locking is transmitted to the abutting portion 51 through the extension portion, and acts on the longitudinal beam 11. The longitudinal beam 11, as a part of the frame 1, can provide sufficient strength and support force. Finally, it is transmitted to the battery replacement actuator 2 as a whole.

[0061] like Figure 3As shown, the battery exchange device is provided with a rack 5, wherein the rack 5 has a plurality of abutment portions 51 arranged along the height direction. The rack 5 is arranged on the longitudinal beam 11. The rack 5 extends in the height direction and can cover various heights of the battery exchange actuator 2 during operation. Thus, by providing a plurality of abutment portions 51, the distance between the abutment portions 51 can be shortened, so that the battery exchange actuator 2 of any height can engage with the abutment portion 51 without moving too much distance when a fault occurs and a stall occurs, so that the brakes can be applied in time.

[0062] like Figure 3 and Figure 4 As shown, a right-angle connecting plate 44 is provided on the side of the battery swapping actuator 2, one side of the right-angle connecting plate 44 is connected to the battery swapping actuator 2, and the other side is connected to a mounting seat 45, wherein the driving part 41 and the clamping plate 43 are respectively connected to the two sides of the mounting seat 45.

[0063] The driving part and the card plate 43 are arranged on the side of the battery replacement actuator 2 through the right-angle connecting plate 44. The right-angle connecting plate 44 can be replaced as a whole, or right-angle connecting plates 44 of different specifications can be arranged according to the corresponding distance with the abutment part 51, so that the card plate 43 can be normally engaged with the abutment part 51.

[0064] like Figure 3 and Figure 4 As shown, the driving part 41 includes an electromagnetic push rod 411 that can move back and forth, and the electromagnetic push rod 411 is connected to the card plate 43. When the electromagnetic push rod 411 is pushed out, it drives the card plate 43 to extend, and when the electromagnetic push rod 411 is retracted, it drives the card plate 43 to retract. The electromagnetic push rod 411 controls the movement by electromagnetic force. Among them, an elastic element 46 is provided on the electromagnetic push rod 411, and the elastic element 46 is initially in a compressed state. When the power is off, the elastic element 46 ejects the electromagnetic push rod 411 through elastic force and drives the card plate 43 to extend, so that the card plate 43 is engaged with the abutment part 51. Under normal conditions, the driving part 41 is energized to generate electromagnetic force to absorb the electromagnetic push rod 411, so that the electromagnetic push rod 411 overcomes the elastic force of the elastic element 46 and retracts.

[0065] The electromagnetic push rod 411 can respond to the control signal in time to drive the extension and retraction of the card plate 43 in time, which is conducive to rapid braking in the event of a fault. At the same time, the electromagnetic push rod 411 is pre-tightened by the elastic element 46, so that the card plate 43 is extended when the electromagnetic push rod 411 does not move, and the card plate 43 is retracted when the electromagnetic push rod 411 moves. Among them, the electromagnetic push rod 411 is controlled by an electrical signal, and the card plate 43 is kept extended when there is no power. Among them, the lack of power includes not only the lack of power in the normal state, but also the situation where the electromagnetic push rod 411 loses power in the event of a fault. Thereby, it is ensured that the card plate 43 can be engaged in time even in the power-off state.

[0066] The elastic element 46 of this embodiment is a compression spring. In other alternative ways, other elastic elements 46 that increase the elastic force in the axial direction of the electromagnetic push rod 411 can also be used.

[0067] like Figure 6 and Figure 7 As shown, the anti-falling device 4 for battery exchange equipment of this embodiment includes a mounting base 45 connected to the battery exchange actuator 2, one end of the clamping plate 43 is connected to the mounting base 45 and can rotate relative to the mounting base 45, a through hole 451 is provided on the mounting base 45, and a connecting element 42 is connected to the electromagnetic push rod 411, and one end of the connecting element 42 passes through the through hole 451 and is connected to the other end of the clamping plate 43.

[0068] In this embodiment, the other end of the card plate 43 is extended or retracted by rotating one end of the card plate 43 relative to the mounting seat 45, so as to engage with or disengage from the abutment portion 51. The card plate 43 is rotated by the driving force generated by the electromagnetic push rod 411, and the motion structure of the entire card plate 43 and the electromagnetic push rod 411 is simple and reliable. At the same time, the extended end of the card plate 43 can respond to the action of the electromagnetic push rod 411 in a timely manner, thereby improving the reaction speed in the event of a fault.

[0069] like Figure 7 , Fig. 9 and Fig.10 As shown, the connecting element 42 of this embodiment includes a connecting cap 421 and a connecting rod 422, the connecting rod 422 is connected to the electromagnetic push rod 411, and the connecting cap 421 connects the card plate 43 to the other end of the connecting rod 422. The connecting cap 421 and the connecting rod 422 connect the card plate 43 and the electromagnetic push rod 411, and the connecting rod 422 and the connecting cap 421 are also very convenient to disassemble, which is conducive to replacing the card plate 43. The electromagnetic push rod 411 will not directly contact and wear the card plate 43, and the parts that are prone to wear are set at the connecting rod 422 and the connecting cap 421 with simple structure and low cost, which can reduce the difficulty of operation and replacement cost during replacement.

[0070] like Figure 7 As shown, the end of the card plate 43 away from the mounting seat 45 of this embodiment has an inclined surface 430. When the locking mechanism 40 is in the first state, the card plate 43 is extended to make the inclined surface 430 horizontal so as to complete the engagement with the abutment 51. During the rotation and retraction of the card plate 43, the inclined surface 430 can be quickly lifted away from the abutment 51 without being obstructed by the abutment 51. When the card plate 43 is extended, the horizontal inclined surface 430 can transfer all the vertical support force to the battery replacement actuator 2.

[0071] like Figure 8As shown, the card plate 43 of this embodiment is provided with a through hole 431, and a groove platform 432 is formed around the through hole 431. The end of the connecting cap 421 abuts against the surface of the groove platform 432, and the connecting rod 422 abuts against the side of the card plate 43 opposite to the groove platform 432. Figure 7 As shown, the end of the connection cap 421 abuts against the groove platform 432 to provide a thrust to the clamping plate 43. The groove platform 432 also has a limiting function, which can always keep the connection cap 421 limited in the groove platform 432 during the repeated retraction and extension of the clamping plate 43.

[0072] The present embodiment also discloses a method for preventing a battery swapping device from falling, which is implemented using a battery swapping device anti-falling device 4 and includes: detecting the lifting and lowering state of a battery swapping actuator 2; and controlling a positioning mechanism 40 to switch between a first state and a second state according to the lifting and lowering state.

[0073] Among them, the lifting state includes the lifting speed of the battery swap actuator 2. When the lifting speed is greater than the preset speed range, the locking mechanism 40 is controlled to switch from the second state to the first state so that the locking mechanism 40 is engaged and connected with the battery swap equipment to prevent the battery swap actuator 2 from moving.

[0074] The present invention realizes emergency braking when the battery swap actuator stalls and falls through a locking mechanism. When the battery swap device loses power, the power device driving the battery swap actuator is damaged, or the speed of the battery swap actuator is too high, the locking mechanism is engaged to lock the battery swap actuator and prevent the battery swap actuator from continuing to move. This prevents the battery swap actuator from being damaged by impact and improves the safety of the battery swap device.

[0075] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
